Duplicate values in column A -> print column B values to Column C (2nd edition)

Hello again.

I had quite a similar problem before and I found help from here. I tried to change the formula to work with my new situation but did not manage to do it.

So I have duplicate values in column A and I would need to print corresponding cell B values to cell C. In the attached example I have written down manually the text in red and i am looking for a formula that could do it automatically.

Thank you in advance for all those who helps because of good will!
